Best Answer

The four main categories of computer hardware are as follows:

Input

Output

Storage

Processing

Input hardware is all the hardware concerning what gets put into the computer. Keyboards, mouse, scanners, digital cameras, and joysticks are all examples of computer input hardware.

Output hardware involves taking the work of the computer and projecting it outward. Printers, as well as monitors and televisions, are examples of output hardware.

Storage hardware allows the computer to hold and maintain a file database. Hard drives, both those installed in the computer and those held externally, as well as USB drives, are examples of storage hardware.

Processing hardware is the real meat of the computer, consisting of the CPU, ROM, and RAM. These things are what make the computer function as a computer.

What are 4 ways in which an operating system controls hardware and software on a computer?

as I remember it the main ways to control peripherals on a computer or computer based systems is software, mediumware, firmware and hardware, things may have changed since i was last at school, but it is worth checking out them all, mediumware may have evolved into firmware by now, but you never know, check it out :) So essentially you have hardware which is controlled by its firmware, the firmware is what the operating system (mediumware)uses to control the hardware, and the software is the part that interacts with the operating system (mediumware) to make it possible for anyone to use the hardware in a nutshell.
